Hi Joe,

Been awhile. You're right. The 3995633 has been listed as the 307 (Chev) gasket for years. I've had them as thin as .016" metal thickness, but they always check at around .020 - 021" in the bead area after they've been compressed. You're also right about the stacking Joe. We went to aluminum rods in a Super Mod years ago with 14.5 to Compression. Of course we needed the extra clearance, and nobody made a race gasket at the time, so we took the advice from Da Grump himself and stacked them. Very fast car for it's day, and never a problem.
